What is coulum barrier? coolum barrier is the electric potential energy.
00:10
It is the electric potential energy of a system, potential energy of a system of two nuclei, system of two nuclei when their surface barely touch.
00:32
Vein surfaces barely and the mathematical expression for cullum barrier is v is equal to 1 .44 multiplied with z1, z2 divided by r mega -elophron volt.
01:00
Where z1 is the charge of the nuclear, of nucleus, j2 is the charge of the particle, which is also the atomic number and of the nucleus and the particles, r is the radius of the nucleus, radius of nucleus, where its value is r0, a, 1 to the power 1 divided by 2 where a is the mass number of the nucleus, mass number of nucleus and as 0 having the value 1 .2 f .m.
01:56
So here this is the mathematical expression to calculate the coulum barrier which is also the electric potential energy.
02:06
We are going to find out the value of cullum barrier for laid 208 when it absorbed alpha particle which means 2 he4 and late having the charge of the atomic number is 82 then it will form p .o.
02:34
84 and 2112.
02:37
As we know that the mathematical expression for the calculating cullum barrier is v is equal to 1 .44 times z1, z2, divided bar m, ev, that is megalachron, hold...
